Abstract
Nowadays there is a strong trend towards considering multiples as genuine part of the seismic response and, therefore, including this in the imaging process.
For surface multiples, this has already shown successful in various applications over the last decade.
For the correct imaging of internal multiples, there is a debate whether removing internal multiples can be more fruitful than trying to image them. In this paper we will show the added value of properly including internal multiples in the imaging stage, where the transmission effect is also being accounted for. In this way the imprint from a multiple-generating overburden is also minimized.
Finally, it will be demonstrated that acquiring data with a broadband acquisition set-up, the effect of internal multiples is already greatly reduced, which inceases the abilities to treat them properly in the imaging stage.
